To all whom, it magjiconoern: I Be known that 1, JOHN Cnonsn, citizen of the United States, and a resident q of i/Vilkinsb'urg, in the count y of Allegheny nally extending arms.

and State of Pennsylvania, f have invent'eiil a new and n se ful- Improvement in Spring Quill- ArmsSupporting"Deviceg of, which the following 1s a specification. I lviy invention relates to means for connecting two relatively membrane ad jacently disposed members, and it; particularrelation to the means for attaching spring quill s amstre s in resilient drivlngdevices', to the ma1n body portion ,of the driving vmember in thevmai-n drive mechanism ofelectric locomotives. I The object of my invention is toprovide a relativelysimple, and inexpensive means for mounting the spring arms upon thesnpporting.men1bertherefor, in such manner that it shall be rigidly fixed in position.-

In'the accompanying drawings, Fig 1 isv a side elevational'view of a portion of a locomotive wheel embed mo in lnventlon;

Fig. 2 is a sectional view taken at I'III' of Fig. 1; and Figs ir3 and dare detail views of structures employed therein.

It has been 'found necess'ary in the manufacture of electricallooomotiv'es, to insert a resilient or shock absorbing member into the driving connection between the wheels and the motor for the purpose of preventingsudden shocks to the motor and slipping of the wheels on the mill: These shock a bsorbing members usuallycomprisea driving and an adjacently disposed drivenmemher in allnement' therewith, eachrof which is provided with arms, the arms fromthe two separate members being alternately .dis posed 'and -extendingintoj the same plane perpendicular to'the axis of the driving and the driven member. The arms from the two members'are connected by helical spring members, the end turns of which are securely held by means of the said longitudi V The spring holding arms are usually separate members attached tothe' d'rivi'ngor the driven members and, "on apcount of the great strains imposed thereon, diff culty has.

By my nvention, I provide a 7 p v I device vwhereby these membersma'ybe rigidlyfiiiedn position, and which, in the event of their "working loose, may readil be tightenedfl Referring to the drawing for a more de tailed understanding of ny invention, 1

showfin Fig- 1, a'locomotivewheel e, provided with arms 6 and a -hub;.7. The wheel is driven bymeans ofa resilienti member 8, one set of endtnrns of which areheld position bya receiving. member 9 mounted on an arm 6; 'The oppositeendyot the spring 8 isheld in a s p ring snpportimg seat which in turn is mounted: on? a' support mg arm 11, radiating fromiadriving diso- 12, which is drivenf-byfthe motorflnot shown).

best shown in Fig. 2,,iThestnds13 are each Q in threaded engagement with the disc 12,. and are provided with a, threaded portjon 15, at the opposite end thereto, and-an in termediate'taperedfportion 16. The tapered portion 16 is disposed within, but in's pa ced relation to the member -v Between the intermediately tapered portion 1.6 ofthe stud and thewalls of; the opening '14, which 'aredof a con'stant 3diamete'r throughout the major portion of their length, is inserted'a bushing 17 as best shown in Figs. 3' and 4. The bushing l7 consists of a'cylindrical member "of uniform outside diameter throughout itsjlngthand having an inside diametergreater aton'e end thereof than at the otherpproviding'aj tapered or wedge shaped cross section'al area. One side of the bushing isp-rovided" with opening 14;, the supporting slot 18 extending its entire length which renders it 'eXpansibleL Referring again to Re 0 6 bushing hel nnos' tion y means ofa lock washer 1-9, and a nut 20 in engagement with the threaded portion f of the stud 13.-

in position in the" disc 12.

p In assembling the spring supporting arms upon the disc, the studs 13 are first placed arm 11 is next so' positioned that the studs 13 project throu h the open ngs therein.

The bushings 17; are next inserted between the tapered portion-so t; the studs and the openings in the arm 11 by being driven therebetween, the end oijthebushinghaving smaller cross-sectional area being presented first. The openings l i in the member'flare counter-sunk at 21, in order to take care of any portion or" the" bushing 17'wl1ichmay have flattened out while being driven into positioin After the bushing is in position,

the lock washer 19 andthe nut 20 are applied, the washer ig 'engaging a1portioni'ii the arm 11, as well jaslthe endof the Washer From-the foregoing description, it will be "apparent to those skilled in'tlie art that as the bushing 17 is driven on the tapered portion of the stud 18, itwill expand," causing itl to engage the'walls'ofthe openings 14, as well as theitapered portion of the stud 13, in a wedgingengagement In the event that thisbushing should wor r loose, it

maybe tightened by turning the nut 20. V7hi1e I have shown but one form of my invention, andhzwe described in detail'but a single application of the same, it will be obvious to' those skilled in the art that it is not so. limited, but that variousfminor modifications and changes may be made therein without departing from the spirit thereof, and I' desire, therefore, that only such limitations shall be placed thereon as are imposed by the prior art or are set forth in the appended claims.
